'1 b all whom it may goncem:

Be it 'known th-atl, WILLIAM BAR'IHOLO- MEW, a .citizen =of the United States .-of America, residing at-Chicago, in thecounty of (look and State of Illinois, have invented certain new and: useful Improvements in b'topMechanismdor Mangles, of which the following is a specification.-

This invention relates to a mangle or ironing machine for fiat work and'particiilarly to means for controlling the driving mechanisms and=lifting therolls from their cooperating steam chests, and comprises a division of my application filed August 17. 1910, Serial #577,677.

The invention has for an object to provide a novel andimproved construction of lifting mechanism for separating the clothed rolls from the cooperating steam chests.-

Another object of the invention is to provide a novel and improved construction of guard board and connections mountedtoco operate with 'atripping device whereby the operation of the machine may be stopped, together with means for resetting or starting the machineafter having been so tripped.

A further object of the invention is to provide a novel and improved construction of safety device adapted to stop theoperation. of the machine and arran ed to operate the raising mechanism for t e rolls.

Other and further objects and advantages of the invention will be hereinafter set forth and'the novel features thereof defined by the appended claims.

In the drawings-Figure 1 is a side elevation of the mangle; Fig. 2 is a detailside elevation of the opposite side of the machine at the feed end thereof; Fig. 3,.is'a to plan view of the roll raising mechanism Fig. 4 is a front elevation of this mechanism; Fig. 5 is a central horizontal section throughthe roll raising means: Fig. 6 is an end elevation thereof looking from theleft of Fig. 4; Fig. 7 is a detail section showing means for retaining the hand lever inposition; Fig. 8 is a side elevation of the safety device. by which the driving power is disconnected; Fig. 9 is a vertical'section on line 9.-9 of Fig. 8; Fig-10 is a horizontal section'on 1ine 1uiu of Fig. 8; Fig. 11 is a similar section on line 11-11 of Fig.8; Fig. 12- is an end elevation of the tripping and resetting mechanism; and Fig. 13. is a side elevation thereof. Like numerals of reference refer to like parts in the several fi res of the'dra'wings. The invention'is a apted for application to any desired constructionof mangle or ironing machine, but 'for the purpose of illustration is here shown in connectionnvith a six roll flat work ironer,'in which the usual clothed rolls 20 are adapted to cooperate with the steam chests 21 as indisated by dotted lines in Fig. 1. These rolls maybe driven in anydesired manner, for instance from a power shaft 22 pro'vided with a pinion 23 which meshes with drivin gears 24 mounted upon the shafts 2 5, whicE shafts also carry pin ons 26 disposed in driving relation to gears 27 upon the rolls by which the latter are rotated in the-same direction and in the usual manner in the art. The rolls 20 are mounted in a movable frame 28 disposed at the upper face of the main frame 29 of the machine and this movable frame is adapted to be shifted to raise the rolls from the steam chests by means of the longitudinally extending rod 30, as shown by dotted lines in Fig. 1. This rod is connected by pivoted lin s movable frame 28 and by meansof similar links 32 withthe main frame 29.' One of the links 32 is provided with a bell crank 33 from which a lifting rod '34 extends downward.

At the feed end of the mangle, the usual feed apron 35 is rovided andadapted to be driven through t e chain and sprocket-connections 36 as shown in Fig. 1. These may comprise a sprocket 37 upon the shaft. of the feed apron roller over which the chain 36 extends and is guided by the idlers 38 w the sprocket 39 disposed upon a shaft driven by geared connections 40 from the roll rotating means. Above the feed apron 35, a finger. or guard board 41- is mounted by means of the brackets 42 as will be hereinafter described. At the delivery end of the machine, a belt or apron bracket 43 is pivot- '31- with the member 71 carried ally mounted at 44 and carries the apron 45 which contacts with the under face of the chests to effect a drying and ironing action during the return of the goods toward the feed end of the mangle in the manner usual in this art; The goods are again returned toward the delivery end of the machine by means of the return apron 46 which cooperates with the under face of the lower ply of the apron 45 and extends to the apron racket 48 where the ironed article is delivered. This bracket, is adapted to be swung away from the final roll and steam chest so as to remove the upper ply of the apron 45 from contact with the under face of the chests by means of a bell crank lever 47 pivoted to the main frame at 48 and connected pivotally to the rod 30 by which the roll carrying frame is lifted. This lever 47 has a link 49 pivotally connected thereto and to the bracket 43. For the purpose of cushioning the movement of this bracket and retaining it in position under proper tension, a rod ,50 is extended downward therefrom and passes throu h a guide 51 upon the frame S29.- This ro issurrounded by a tension spring 52 which bears against the guide at its lower end and contacts with i an adjustable collar 53 securedto the rod at its upper end.

The roll lifting rod 34 is provided at its lower end with a cam sleeve 54 adapted to embrace a cam 55 disposed upon the shaft 56 which is also provided with a sector 57 meshing with a worm 58 upon the countershaft 59, as shown .in Figs. 3, 4, 5 and 6. The countershaft is provided at one end with a beveled gear 60 meshing with a cooperating gear 61 carried by the shaft 62 which is provided with a hand wheel 63 by which the rolls may. be raised or lowered by hand when desired, or if the power connections are disconnected. The opposite end of the countershaft 59 with a beveled gear 64 which meshes with the oppositely disposed beveled gears 65 and 66 which are loosely mounted upon the shaft 67 provided with a driving sprocket 68. Slidmgly secured upon the shaft 67 is a clutch member 69 provided at its opposite sides with the clutch faces 70 adapted to coii rate with the clutch y the beveled ears 65 and 66. The shaft 67 is adapte to driven from the power shaft 22 by means of the chain 72 extending to the s rocket 75 upon the shaft 74. This shaft a so carries a sprocket 75 from which a driving chain 76 extends to the sprocket 68 upon the shaft 67 as shown in Fig. 1.

For the purpose of shifting the clutch 69 to a neutral or nonoperative position when the rolls reach the limit of their movement either toward or from the chests, a shifting is provided lever 77 is pivotally mounted at 78 upon the supporting bracket 79 and has a bifurcated portion embracing the clutch 69 in the usual manner. This lever is provided with a lateral crank arm 80 having at its outer end a sleeve 81 mounted to slide upon a depending rod 82 which is secured to the rod 34 by a bracket 83. The lower end of this rod is threaded and provided with adjustable stop nuts 84 thereon at opposite sides of the sleeve 81. It will be seen that in the reel rocation of the rod 34, the stop nuts Wlll enga e the crank arm 80 and operate the clutch member automatically when the proper travel has been secured.

Under some conditions, it is desirable to shift the clutch manually to actuate the rod 34 in either direction or entirely disconnect the ower therefrom. This may be convenieutiy accomplished by means of a rock shaft 85 mounted in bearings 86 upon the main frame and provided with an operating lever 87 as shown in Figs. 3 and 4. The shaft 85 is provided with a. crank arm 88 which, at its outer end, is formed with a slotted connection 89 with a lever 90 pivoted at 91. The lower end of this lever is provided with a pin working in slotted connection 92 in the clutch lever 77 in order to shift the latter by the oscillation of the rock shaft 85. 'For the pn ose of retainjusted position, a holding sector 93 is adjustably secured thereon and provided upon its curved outer. face with a lug or projecticn 94 adapted to seat between the ends of the looped spring 95 secured upon a fixed part 96. By this means, the shaft and its operating lever may be securely. retained in position to render the clutch inoperative.

The guard board 41 is pivoted at upon the bracket 42 and provided with a crank arm 101 from which a trip rod 102 extends to a lever arm 103 on shaft 107. The shaft 107 is rovided with a bifurcated crank arm 110 a a ted to actuate an auxiliary clutch 111 sli ably mounted upon the shaft 112. This shaft and the other members of the safety' device for disconnecting the ower are supported at their outer ends in tiie bearing bracket 113. The shaft v112 is provided with a loosely mounted pinion 114 thereon, provided with a clutch memher 115 to coiiperate with the'clutch 111. The hub of the pinion 114 is rovided with a beveled gear 116 which mesiies with a cooperating gear 117 mounted u on the shaft 118. The hub of the gear 11 has secured thereon an eccentric 119 which is adapted to travel in contact with a shifting lever 120 pivoted at its lower end 121 to the bracket 113 and bifurcated at its upper end 122 to embrace a clutch member 123 which is slidingly keyed upon the power shaft 22 ing or holding the rock sha t 85 in its adand cotiperates with a clutch member 124 carried by the driving pinion 125 loose upon the power shaft. T e clutch members 123 and 124 are normally held in en gement by the vs ring 126 surrounding tg power s aft an bearing upon the clutch 128 at one end and at its opposite end against the bearing box 127 of the bracket 113. The pinion or gear 114 is adapted to be driven y a meshing contact with one of the rs 24 for driving the rolls, as shown in 2 and 9. By this construction, it will e seen that if the shaft 107 be tripped, the clutch 111 will be moved into enga ment with the gear 114, thus causinga 'ving of the parts to rotate the cam 119 in contact with the shifter lever and. thus move the clutch 123 out of engagement and stop the driving of the parts.

After the operation of the trippin shaft, it is desirable to reset the parts and t is may be accomplished by rotating the shaft 118 to bring the cam 119 in such position that the spring 126 ma move its clutch members into contact. his may be accomplished by means of a hand wheel slidingly keyed upon the shaft 118.

Under some conditions, it is desirable to automatically and simultaneously raise the rolls and remove the aprons from the chests as the power is disconnected and for that pur ose the lever 134 is mounted upon the she 107. The lower end of this ever is connected by a rod 135 with a depending arm 136 carried by the rock shaft 85 at the opposite side of the machine, as shown in 1 1, in order to automatically operate the re raisin mechanism. The resettingshaft is moun in bearings 138 carried y the main frame and the trip shaft 107 is supported in depending bearings 139, as shown in Fig. 2.

In the operation of the invention, the articles to be ironed are fed between the rotating rolls and steam chests to be ironed on one side and are then received by the apron 45 and carried back in contact with the'under face of the chests to further iron and dr the articles and are finall returned tower the delivery end between the parallel aprons extending to the pivoted apron bracket. If at any time it is desired to stop the operation of the machine,.the rolls are lifted from the chests to prevent scorching or injury to the clothing thereof and this raising movement automatically swings the a ron bracket away from the final roll and c est, thus dropping the a ron from contact with the under face of t e chest automatically. This same action occurs in the operation of the guard board as, if it be pressed inward by contact with the hand or fingers of the operator, the shaft 107 is operated and through its connections, the power is disconnected, to stop the operation of the machine and automatically raise the rolls from the chests and drop the a rons therefrom. The extent of movement 0? the roll raising device is automatically controlled and the hand operatinglever for shiftirIifi the controlling clutch. adapted to be fir y held in position. .The rock shaft controlling the clutch for the raisin mechanism is adapted to be operatedeit er bya hand lever or by the guard board. The parts of the safety device for unclutching the power throng: the movement of the guard are adapted to reset for starting the, machine byreturning the controlling cam: to proper position. The trip shaft is automatically reset by the weight. of the guard board and the inward movement of tbisboard effects the operation ofthe lever system above described for disconnecting the power and for raising the rolls I The invention presents a very etn'cient and economically constructed mechanism for controlling the relation of the rolls and apron to. the steam chests and also to guard against injury. to the operator in the introduction of goods'to the rolls at the feed apron.
